Abstract
A method for automatically inspecting a surface of a solid object such as, for example, a surface of an aircraft; the method using a step of blurring said surface represented in the form of a depth map image, followed by three successive derivation operations applied to said image. The invention also relates to a system configured to perform the method. Advantageously, it is thus possible to automatically detect planarity defects in a surface of an aircraft with a level of accuracy not yet achieved.
Claims11
A method for automatically inspecting the condition of a surface of a solid object, said method comprising:
- obtaining first information, representative of the shape of the surface of the solid object, in the form of a map of distances between said surface and a sensor of a measuring device,
- obtaining second information by applying a blurring filter to said first information,
- obtaining third information by a first derivation operation of said second information, using a first derivation operator,
- obtaining fourth information by a second derivation operation of the third information, using a second derivation operator,
- and said method further comprises:
- obtaining fifth information by a third derivation operation of the fourth information, using a third derivation operator, then,
- detecting a defect in said surface using a defect detection module based on the fifth information obtained.
An automated inspection system for inspecting the condition of a surface of a solid object, said system comprising electronic circuitry configured to:
- obtain first information, representative of the shape of a surface of a solid object, in the form of a map of distances between said surface and a sensor of a measuring device,
- obtain second information by applying a blurring filter to said first information,
- obtain third information by a derivation operation of said second information, using a first derivation operator,
- obtain fourth information by a second derivation operation of the third information, using a second derivation operator,
- obtain fifth information by a third derivation operation of the fourth information, using a third derivation operator, and,
- detect a defect in said surface, using a defect detection module, from the fifth information obtained.
